tan of a number
AI agents call tan to retrieve information from MCP Server & Client Test Environment without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tan tool computes the tangent of a numeric input. This is a stateless mathematical function that reads an input and returns a value, with no data modification, execution, or external interaction.
From the tool's definition 'tan of a number' — pure mathematical operation with no side effects
Attacks that exploit this kind of access
tan of a number. It is categorised as a Read tool in the MCP Server & Client Test Environment MCP Server, which means it retrieves data without modifying state.
Register the MCP Server & Client Test Environment MCP server in PolicyLayer and add a rule for tan: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches MCP Server & Client Test Environment. Nothing to install.
tan is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the tan rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for tan. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
tan is provided by the MCP Server & Client Test Environment MCP server (mayur11235/lets-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
